Hi @Anonymous,
Could you please share a bit more about your scenario?
Do you want to display a Visio chart within a PowerApps app?
If you want to display a Visio chart within a PowerApps, and interact with other controls in your app, I afraid that there is no way to achieve your needs in PowerApps currently.
If you would like this feature to be added in PowerApps, please submit an idea to PowerApps Ideas Forum:
https://powerusers.microsoft.com/t5/PowerApps-Ideas/idb-p/PowerAppsIdeas
Currently, as an alternative solution, you could consider take a try to create a Visio chart within Power BI report using Visio Custom Visual functionality, then embedded a PowerApps app within the Power BI report using PowerApps Custom Visual functionality, after that, you could pass parameters from your Visio Chart to this embedded app.
More details about the creating Visio chart using Visio Custom Visual functionality in Power BI, please check the following blog:
